HTML5 Geolocation is used to locate a user's position
Locate the User's Position
The HTML5 Geolocation API is used to get the geographical position of a user.
Since this can compromise user privacy, the position is not available
unless the user approves it.
Browser Support
Internet Explorer 9, Firefox, Chrome, Safari and Opera support Geolocation.
Note: Geolocation is much more accurate for devices with GPS, like iPhone.
Using Geolocation
Use the getCurrentPosition() method to get the user's position.
The example below is a simple Geolocation example returning the latitude and longitude of the user's position:
Example
<script>
var x=document.getElementById("demo");
function
getLocation()
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showPosition);
}
else{x.innerHTML="Geolocation is not supported by this
browser.";}
